The Vihtavuori N150 Smokeless Rifle Powder is a single-base rifle powder for handloaders working on accurate loads. It comes from a lineup that spans a range of burn rates, so you can pair it with different bullet weights and cartridge sizes. The temperature-stable formula helps keep your loads consistent from one season to the next. It's REACH compliant, and sealed containers have a shelf life of at least 10 years.
